Younger Dryas impact hypothesis

Target entity: Younger Dryas impact hypothesis
Context triple: [Magicians of the Gods, subject, Younger Dryas impact hypothesis]

• A. Younger Dryas cold event
  The Younger Dryas cold event was a brief, abrupt return to near-glacial conditions about 12,900–11,700 years ago that interrupted the general warming trend at the end of the last Ice Age.
• B. Holocene catastrophic flooding of the Black Sea
  The Holocene catastrophic flooding of the Black Sea is a hypothesized prehistoric deluge in which Mediterranean waters are thought to have rapidly inundated the Black Sea basin, potentially inspiring ancient flood myths.
• C. An Inquiry into the Original State and Formation of the Earth
  *An Inquiry into the Original State and Formation of the Earth* is an 18th-century geological treatise by John Whitehurst that explores the Earth's structure, history, and the processes that shaped it.
• D. Berserker hypothesis
  The Berserker hypothesis is a proposed solution to the Fermi paradox suggesting that self-replicating killer probes or hostile civilizations systematically destroy emerging intelligent life in the galaxy, explaining our apparent cosmic silence.
• E. The Age of the Earth
  The Age of the Earth is a landmark 20th-century geology book that helped establish modern estimates of Earth’s age using radiometric dating methods.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Younger Dryas impact hypothesis
Target entity description: The Younger Dryas impact hypothesis proposes that a comet or asteroid impact around 12,800 years ago triggered abrupt climate cooling, widespread wildfires, and megafaunal extinctions at the onset of the Younger Dryas period.
